I purchased vehicle used on 2/14/2018. Carfax stated no outstanding recalls. After about one year, very occasionally, when shifting from park to drive, the gear would not engage until the process was repeated. Just recently, while highway driving, both "service engine" and "transmission" warning lights appeared on the dash. This was followed by a near total loss of power and an occasional stall. This obviously created a dangerous safety hazard for me and the other drivers in my area. I took the vehicle to the local ram dealership (peacock - bluffton, sc) and (after 5 days) was told I needed a new "transaxle range sensor wiring harness" ($700. +/-) and a powertrain software update (warranty). Some research revealed a recall by fiat-chrysler (8/2016) for the wiring harness - s55 / the federal safety agency 16v‑529. According to the dealer, fiat-chrysler will only honor this recall for a period of 2 years from date of issue. Further research revealed that the federal safety agency requires recalls be honored for a "reasonable" amount of time, suggesting that 10 years is "reasonable". This is day #8 as the vehicle remains in a bay at the dealership. I am looking from some guidance on how to proceed.

Car was hesitating when starting from a stop. Once in a while the car would jerk back or forward. While driving the check engine light came on and I lost power. The car would only go about 5 MPH. Brought back to dealer where he checked the light code and came back as transmission sensor issue. Dealer reset the code and I was ok for a week. Code came back on while driving. Brought back to dealer and they said they would update the software. After about a week the code came back again. This time they gave it to another dealer to look at and they found that it was a bad valve body in the transmission. I have been without the car for a month now as they wait for the back ordered part. All times the light came on I was on a street or route doing under 50 while driving forward

We own a 2015 ram promasters. While driving on the freeway at various speeds. Tech experienced a sudden loss of power. On the dash appeared a yellow check engine light and a red symbol ( ! ). A message read "service required - transmission service". As the tech attempted to exit the freeway, afraid that the van might stall with incoming traffic. He made a safe exit off the freeway. Pulled over, turned off ignition and was able to restart the car in hopes that the trouble would clear. The red symbol ( ! ) disappeared and power was restored. Was able to drive back to company.

Four times in one day the vehicle transmission and engine warning lights and alarms were activated. Immediately, the vehicle loss power. In one instance, this happened while I was encountering vehicles entering and exiting a highway ramp. The immediate slowing almost caused a collision as vehicles accelerating off the entry ramp and merging into my lane suddenly had to slow or take action to avoid rear ending me. This occurred two more times before I could get the vehicle to the service department. A similar incident happened when I first purchased the vehicle and was advised it was a programming issue. I had received a recall notice, but it advised the parts were not available. It advised I would be notified when the parts are available. The recall did not advise I should not drive the vehicle. I did deliver the vehicle to the servicing dealership advising I would not drive the vehicle until it has been repaired. I was advised by the service department that the part had been ordered. They advised they thought the part was available but could not confirm it. I have been without the vehicle for over two days and have not received any information as to when the vehicle will be repaired. With the loss of power, the vehicle seemed to go into neutral two times. The other two times it seemed to lock into high gear and once you had to slow or stop it could not accelerate. I managed to get off highway twice and restart the vehicle but the other two times I had to restart the vehicle in traffic. It would work properly for a few minutes after restarting but the engine light would stay on.
